Samsung LCD TV LN40A530P1F Will not turn on

Samsung LCD Samsung LCD TV LN40A530P1F will not turn on. It acts like its not even receiving any power. We have gotten it to come on after pressing the power button a ton of times over and and over again. The red light in the bottom right corner is not even on. We have checked all of the power supplies, the cords, the outlets etc. It also is making an extremely high pitched noise even when its off. Any in home repair we could do? If not, is it worth it to get it repaired or get a new one? We are on a tight budget either way so the cheapest option within reason would be the best.

It's the capacitors on the power supply circuit board. Easy fix. Less than $5 for parts. DO NOT ATTEMPT unless you know what you are doing though. Opening up the back of TV will void warranty, and you can get shocked...even if tv is unplugged. The capacitors can still hold a massive charge.

Unplug tv, then hold power button (30 seconds) to drain power from capacitors. Open up tv, and look at the capacitors on the power board. If the tops are bulged up then they are bad, and need to be replaced. Replace with caps of same value, or a few volts higher, but be sure the uf rating is the same. remove old caps using solder gun, and solder new caps in place. make sure you have + & - sides positioned correctly.
